Variable voltage allows you to raise or lower the amps going to your topper or atomizer. A normal eGo battery is fixed and about 3.3 ish volts..........with a VV, you can raise that to find what is sometimes called, "the sweet spot" of your juice.

Your toppers have a resistance which basically is how conductive the material is that heats your juice and some of these coils are rated higher than a 3.3 battery may be considered to work well at. In my experience, some juices taste much better at a higher voltage. So, basically; it gives you options.

Variable Wattage is another setting or different mode than Variable Voltage so when you see something that is VV/VW, it does both....but it is still kinda the same principle. I would explain it as asking your GPS to "avoid highways" or "take highways". You still get there, it is just a different way.

Clouds are based on coils and airflow.

I am, of course....simplifying this.

What does variable voltage do to the vaping experience?

Does it change the flavour and vape cloud?

It intensifies the vapour production. More often than not, it will improve flavour, yes!

It also assists in making clouds... sure.

I use it because higher power vaping increases the "presence" of vapour as I inhale.

To understand the process in reverse, compare an eGo e-cig to a Nicolite or similar, as they vape at low power.

More vapour = more nicotine, hence why people enjoy lower nicotine liquid but huge clouds. I approve of that too. :)

Another analogy: Boiling water on the stove. Low heat does not produce much steam (vapor). Higher heat produces more steam (vapor). More heat = more vapor.

Some vapers like to re-create the warm smoke that a cigarette has; using higher voltage can help accomplish that. Others like to create the cooler/smoother smoke that a hookah has; again, variable voltage can help accomplish that. It gives you more options than a fixed-voltage output battery.

Many e-liquid flavors will taste better at a particular voltage, their so called "sweet spot". IMO, fruit flavors have more flavor in the lower voltage range (too much and they taste burnt). Other flavors, such as coffee or tobacco flavors have better flavor in the mid to upper voltage range. This is all subjective to the individual person, and your results may vary from my own.

I like the higher voltage to improve throat hit, too. But there's only about a hair's difference with my juice, between "awesome throat hit" and "horrible burnt taste" so I have to be careful.

Also I like to turn the voltage all the way down to lowest in the morning when I first get up. I love throat hit, but can't take it in the morning without coughing up a lung just like with cigarettes.

Yep, as much or more than vapor production, some flavors change fairly dramatically depending on what power level you vape them at.

As an example, one of my favorites, "Deadly Sin" tastes like a rice-krispies treat at low power, as you raise the voltage the cinnamon starts coming out stronger, it starts tasting like a cinnamon bun, and at high power, mostly just like cinnamon. I like both the "Rice Krispy" and the "Cinnamon bun", sometimes I want one, sometimes the other.

VV also helps you deal with different-resistance heads; you can crank up the voltage if you have high ohms, back it down for low.

IMHO, though, the taste is the reason you want VV (not the amount of vapor, unless your taste buds are really dead).

Variable voltage is really a misnomer. It is really regulated voltage which you can control.

With just a battery, the voltage will vary while you are vaping; it will gradually decrease until you recharge the battery.

A variable voltage battery has electronics to boost voltage so that you can keep the voltage steady while you vape; additionally you can adjust the voltage.

High voltage can produce more vapor; it can also dry out your coil/wick and cause burning glycerin which makes you go "ACK!"

Variable voltage is superceded by variable wattage (VW).
With VW, you set the power level in watts, and the electronics measures the resistance of your coil and adjusts the voltage to get that wattage. This means you can usually swap out your atomizer coil without having to worry about small differences in resistance.

I need it around 5 - 6 watts to get a balanced flavor from tobacco that resembles smoking. On the other hand, I've found fruit flavors are often better at lower watts.

You can also get around that issue altogether by carefully choosing the resistance. I use 2.6 - 2.8 ohms for a 3.7v battery as a compromise, though most people seem to prefer using 2.2 - 2.4 ohm as a minimum.
